FRANK J. BRUNELL, or CHICAGO, :minors COUNTERWEIG-HT,

To all/whoa?J I? may concern: Be it known that I, FRANK J. BRUNELL, a 1

I .citizen of the United States, residing at Chi- A shoe of greater or less Width', depending upon I'whether :the verticalguides are of wood, or metal, is usually: fashioned in each end of the weights, and made smooth, s o

. that they will slide voverfthe vertical guiding surfaces with aslittle resistance, due to friction, as may be, thereby minimizing `wear of the contacting surfaces,

The cheapest grade of iron is as well vadapted for weights, such as that which is made of worthless scrap, comprising largely, discarded old tin cans, and the like, as va higher quality. The difficulty encountered 'in' attempts to use it is that it isvery refractory and difficultto tool land since the castings made: of it wholly are exceedingly rough, the charge for labor required to finish the guide surfaces is greater than the difference in the cost of the twol grades of metal.

The result isthat a higher grade -of iron A has heretofore beenI used entirely for the purpose. Even when a more expensive soft iron is used, and thevshoes are made integral parts of the weights, the inconvenience of handling the -entire mass, toV tool the shoe, increases the productive cost for labor, as

I,tvell as for material..

One ofthe objects of my inventlon is to make Weights, of the character described, of the cheaper grade of iron and to make separable shoes, of relatively light weight andi size, of a superior metal. I then clean andy smooth up the' shoe surfaces by pickling or tumbling or both,f,` until they are practically as smooth as when finished by more expen- ,sive tooling.

yAfter the shoes arel fitted, they are then' n placed in a mold 'and the body part of the weight, constituting the lower grade of iron specification of Letters Patent. Applica/cien mea rune 5,1918. serial No. '238,296.

is cast around portions of the shdes to hold them permanently attached' to said body 3 part. v s

Other and'more specific objects of my invention will become readily apparent to persons skilled in .the art from aA consideration of the following description when taken in 4conjunction with the drawings,`wherein:

. Figure 1v is a'broken-in-two elevation of the weight, showing one part in section, taken on line 1-1 o f 2, and the other part inelevation.l

Fig. 2 is a planrview showing a part in sectiorri Fig. 3 ,is an'isometric perspective View of lthe shoefbefore'being placed in the mold joined tothe main body part of the weight. i

to be In all the viewsthe same reference vcharacters are employed to indicate similar parts.

The shoe :consistsofa U-shaped part 5` toY providedy .with ayoke'portion 6 and `two projectinglearsror prongs 7 and 8, forming between-- thef prongs a space 9, within which is to be contained the vertical guides upon which the shoesl move when they are performing the functions intended. In the center of the yoke part 6, and projecting rearwardly thereof, is a leg l0, provided with an incut panel 11, on each side, to receive portions of the cast iron weight 12, when the latter is molded around that portion of the shoe. The prongs 7l and 8 are outwardly enlarged, as at 13, so as Ito hold them more firmly in the mold and to prevent them from floating or being disturbed by the washing effect of the liquid iron when the body part 12 is being cast. Y

f The incut panel 11 serves to hold the two different qualities Aof metal firmly together and does not weaken the shoe to any extent, as any contraction ofthe hotter metal on either side of the rearwardly projecting part 10, tends to apply a crushing strain to this part rather than to produce an edect to vtear it asunder, as ity would if a hol'ej were made 'through the :projection V10.- A
